Step-by-step explanation:
Answer – Angle Measure
Generally speaking, when similarity transformations are performed on a triangle, the angle measure is preserved, whereas the length of the sides may be enlarged or reduced depending on the scale factor of the transformation, thus giving rise to similar triangles with corresponding angles that have exactly the same measure and corresponding sides that are proportional.

The perimeter of a rectangle is (2 lengths) plus (2 widths).
If one side is missing, then it sounds like you still have enough information
to know what the length and the width are. Just take each number and use
the first line up there /\ to calculate the perimeter with them.
Answer: 8 feet
Step-by-step explanation:
Draw a right triangle and label the sides using the given information. (Drawing below) Use pythagorean theorem to find the missing length:
a^2 + b^2 = c^2
(building)^2 + (missing piece)^2 = (ladder)^2
6^2 + x^2 = 10^2
36 + x^2 = 100. subtract 36
x^2 = 64. square root of both sides
x = 8
